[Serusers] LINUX gateway with RTP Proxy & STUN Server

Hi Thanks for the answer on the other subject Now, a new question I think that I have the worst scenario I have an Intranet with a RH 6.2 working as a Gateway/Firewall with a 512Kb ADSL with 2 switchs 3Com & 1MB w/Cisco 575 LRE with 5 IPs & 1 swithc 3COM I don't mix both connection If I connect a device on the Cisco 575 with one of the public IPs, obviously, everything works If I connect a device to the switch (Gateway/Firewall), the problems begin I doing the test with a soft phone (X-Ten Lite) with a GrandStream HandyTone ATA286 & CiscoATA With the X-Ten I can login, and I can make calls and "send" audio, but I can't receive calls or audio when I make the call With the Cisco ATA all works if I change the IP everytime I connect to ADSL and use UREDIR to redirect ports to the internal IP (not a good solution) With the GrandStream I can't login :( I allways receive both IPs on SER "check_via_address(xxx.xxx.xxx.xxx, 192.168.0.76, 0)", and SER reject the registration ----------------------------------------------------- if (search("^(Contact|m): .*(a)(192\.168\.|10\.|172\.16)")) { # allow RR-ed requests, as these may indicate that # a NAT-enabled proxy takes care of it; unless it is # a REGISTER if ((method=="REGISTER" || ! search("^Record-Route:")) && !( src_ip==192.168.0.0/16 || src_ip==10.0.0.0/8 || src_ip==172.16.0.0/12 )) { log("LOG: Someone trying to register from private IP again\n"); sl_send_reply("479", "No se permiten conexiones desde IP privadas" ); break; }; }; ----------------------------------------------------- Now the question: What I need to get a "clear" connection to SER with public IP from my Intranet ?
